COMBINED VALVE AND SPRAY-NOZZLE FOR HYDROCARBON-BURNERS.

Specicaton of Letters Patent.

Patented Apr. 21, 1914.

Application filed November 16, 1912. Serial No. 731,783.

To all whom t may concern.'

Be it known that I, GARNET W. COEN, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Combined Valves and Spray-Nozzles for Hydrocarbon-Burners, of which the following is a specification.

rlhis invention relates particularly to improvements in the valve and spray tip con* struction of a former application tiled by me February 5, 1912, Serial Number 675,662, entitled Hydrocarbon burners.

The main object of this invention is to construct a spray or discharge nozzle which is capable of producing a flat spreading flame, and in means for controlling the volume of oil discharging from the nozzle without reducing the pressure or velocity of same.

A further object of the invention is generally to improve the burner so as to increase it-s utility, durability and efficiency.

The invention comprises details of construction which will be more fully explained by reference to the accompanying drawings, in which- Figure l is a longitudinal section of an oil burner showing the application of the invention. Fig. 2 is a perspective view of the device partly in section. Fig. 3 isa cross section of same on line X--X. Fig. 4 is a perspective view showing a slight modifica tion. Fig. 5 is a cross section on line V--V,l

Fig. 4. Fig. 6 is a perspective view of the reciprocating valve. Fig. 7 is a side elevation of the nozzle body. Y

The object of this invention is to provide means for producing a flat and spreading flame, without the aid of an atomizing agent, together with means for regulating the volume of o-il supplied to the flame, wit-hout reducing the pressure or velocity of the oil entering the burner; this being very essential where certain types of boilers are used.

Referring to Fig. 1 of the drawings, A indicates in general the application of the combined valve and spray nozzle to a standard oil burner. The device consists of a cylindrical main body portion 2 having an annular flange 3 and a reduced portion 4,

the function of which will be later described. The cylindrical body portion is centrally slotted longitudinally, as shown at 5; the slot being of such a depth as to communicate at 6 with the center of a slot 7y cut or otherwise formed transversely `across the front face of the nozzle and made shallower each way from the opening 6. The slot 7 is positioned at right angles to slot 5 and is formed for the purpose of shaping and directing the oil spray discharging through the passage or opening 6 connecting the slots 5 and 7. For the purpose of controlling the volume of oil discharging at this point, I have provided a valve 8 slidably mounted in the central slot 5. The valve 8 may be re ciprocated to control the volume of oil by any suitable means, or preferably, as shown in Figs. l and 2, by fo-rming a threaded portion 9 on the outer end of the valve, which is engageable with an internally threaded sleeve 10 secured to a turnable valve stem l1 mounted in the outer portion of the oil burner as shown. For the purpose of limiting the outward sliding movement of the valve member 8 and also for the purpose of preventing clogging of the slot 5, I have provided the lateral extensions l2 which will become engageable with a stop 13 secured upon the reduced portion 4 of the main body. The forward end of the valve 8 is also provided with a central end eXtension 14, which is so positioned as to enter the discharge opening 6, and it will thus clear a free passage at this point at all times.

In an oil burner constructed as here shown, it is preferable to pass the oil through a heater under pressure; the heated oil under pressure entering the main burner through the intake pipe 15. The object in heating the oil is to thin it, producing a freer flow of the oil and making it possible to provide a -mor-e sensitive adjustment. From here it passes through the tube or nipple 16, as indicated by the arrow, and enters the slot 5, as indicated by the arrows a. The o-il entering from both sides of the slot 5, as shown, will discharge through the central opening 6 and slot 7 and will form a fiat spray in the plane of the opening 7. The oil entering from bot-h sides, as shown by the arrows a, will have a tendency to equalize and balance the discharging spray and thus tend to produce an even, uniform, steady iiame. V i

By referring to Fig. l of the drawings av slight modification of the device is shown.

This construction is particularly desirable where it is desired to produce a larger volume of flame without increasing the size of the nozzle. This is accomplished by formingtwo discharge slots, as 7 and 7b, which communicate with a vertical slot 5t. For the purpose of insuring a sufficient supply of oil where two discharge openings are supplied, it has proven desirable to provide a secondary supply slot, as 5b, formed at right angles to the main slot, as shown. The valve member indicated at 8aN is in this instance supplied with Jfour wings 17, which wings enter the diiierent slots 5 and 5b. The valvey may be reciprocated as in the former instance by the mechanism indicated in Fig. l, and the cleaning of the slots may be ac` complished in a similar manner by providing the lugs 12a. For the purpose of positively retaining the nozzle in a iXed position with relation to burner and for the purpose of preventing any circumferential movement between the different parts, I have provided the nozzle front with a pair of inwardly projecting lugs or pins 1S, which are sol positioned as to register with slots 19 formed in the pipe or nipple 1G, thus providing a positive adjustment and preventing circumferential movement. The nozzle is secured in place by the screw cap 2O.V From this it can be seen that a simple, compact, eliicient device is produced in which' the volume of oil discharging from the nozzle can be easily regulated by simply adjusting the position of the valve with relation to the discharge opening, thus eliminating the necessity of reducing the velocity or pressure of the oil at the point of discharge.

The apparatus is simple, compact and positive in operation and takes no more space than similar devices. The materials and finish of the several parts of the device are such as experience and judgment of the manufacturer may dictate.

I wish it understood that various changes in form and proportions may be resorted to, and that I do not wish to limit myself to the specific design here shown.

Having thus described my invention, what I claim and desire to secure by Letters Patent isl.
